FALSE-TEETH ATTACHMENT.

Specification of Letters Patent.

Patented July 12, 1921.

Application filed August 24, 1920. Serial No. 405,569.

To all whom it may concern: 7

Be it known that we, BENJAMIN ELIsBnRc and lVILL AM SHEEF, both citizensof the United States, and residents of the city of New York, borough ofBronx, county 0 Bronx, and borough of Brooklyn, Kings, respectively, inthe State of New York, have invented a new and im roved False-TeethAttachment, of which the following is a full, clear, and exactdescription.

This invention relates to false teeth, and has reference moreparticularly to an attachment adapted to secure false teeth in the mouthof the wearer.

As is commonly practised, the plate holding the false teeth is providedwith a soft rubber suction cup which is adapted to engage the roof ofthe mouth so as to maintain the false teeth in position. However, thismethod of fastening is uncertain, and as a result when a person sneezesor coughs, it frequently happens that the false teeth will break loosefrom the fastening, and be thrown from the mouth. 7

An object of this invention, therefore, is to provide a means ofsecuring false teeth to the wearer which will prevent the false teethfrom falling out when a person sneezes or coughs.

Reference is to be had to the accompanying drawing forming a part ofthis specification, in which ltllS understood that the drawingillustrates only one form of the invention, and in which Figure 1 is aside elevation of a set of false teeth with our improved fastening meansin position. i V

Fig. 2 is a central sectional view of the false teeth 1n position in apersons mouth.

Fig. 3 is a sectional view on a large scale through the fasteningdeviceon the line 33 ofFig. 1. r

Fig. 4 is atop view on a large scale of the fastening device. H

Referring to the accompanying drawing by numerals, 1O indicates'theplate of a set of false teeth around the edge of which are secured byany suitable means, false teeth 11. Our improved fastening device forsecuring the plate 10 to the roof 12 of a persons mouth consists in ahinge leaf 13; embedded in the upper edges 14 of the platelO, said hingecounty of leaf being connected to a second hinge leaf 15 by a hinge pin16. A coil spring 17 embraces the hinge pin 16 and normally tends topress the hinge leaf 15 inwardly toward f the gums 18 in a personsmouth. A pad 19 of any soft material such as rubber, cork, etc., issecured to the hinge leaf 15 by offset fingers 20 which extend into thepad 19. The

' pads 19 prevent pain in the gums 18 due to the pressure of the spring17 The outside surface of the edges 14; of the plate 10 are preferablysmooth and conform to the shape of the hinge leaf 15 so that the personscheek 21 is not injured by contact with our fastening device. It isunderstood that instead of the hinged fastening device, we mightsubstitute a flexible member which would serve the same purpose. I

We would state in conclusion that while the illustrated exampleconstitutes a practical embodiment of our invention, we do not limitourselves strictly to the mechanical details herein illustrated, sincemanifestly the same can be considerably varied without departure fromthe spirit of the invention as defined in the appended claims.

Having thus described our invention, we claim as new and desire tosecure by Letters Patent:

1. In a device of the character described, the combination with a dentalplate, of means carried thereby for maintaining the plate in position inthe mouth of the wearer, comprising elements hinged to the oppositesides of said plate and means for normally effecting the movement ofsaid elements toward each other to cause the same to engage and grip thegums.

2. In a device of the class described, the combination with a platesupporting false teeth, of a pair of pivotally connected hingeleaves,'one of said hinge leaves being secured to the edges of saidplate, a pad secured to the other of said leaves adapted to engage aBENJAMIN nL IsBERe."
